Solar Rebates and Feed-in Tariffs in Australia 2026: The Complete Homeowner Guide

By Emma Wilson | 2026-08-02 | Category: Solar

A 2026 guide to Australian solar rebates and feed-in tariffs — how the federal STC scheme, state incentives, and export payments actually work.

If you're weighing up going solar this year, understanding solar rebates and feed-in tariffs in Australia 2026 is the single most important step before you sign a contract. Between the federal Small-scale Renewable Energy Scheme, state-based top-up incentives, and retailer feed-in tariffs that vary wildly from one company to the next, the amount you actually save can differ by hundreds of dollars a year depending on how well you understand the system. This guide breaks down what's on offer, how the numbers work, and what to check before you commit.

How Solar Rebates and Feed-in Tariffs Work in Australia in 2026

There are two separate pots of money worth knowing about, and they work completely differently:

The upfront rebate — a discount on the cost of installing a solar system, applied at the point of sale by your installer.
The feed-in tariff (FiT) — an ongoing per-kilowatt-hour credit on your electricity bill for excess solar power you export back to the grid.

Both matter, but they're often confused. The rebate affects your payback period; the feed-in tariff affects your bill savings for as long as you own the system.

The Federal Rebate: Small-scale Technology Certificates (STCs)

Most of the "solar rebate" Australians hear about is actually the Small-scale Renewable Energy Scheme (SRES), a federal program that creates Small-scale Technology Certificates (STCs) for eligible solar installations. Your installer calculates the number of STCs your system generates based on its size, your location (zone rating), and the number of years remaining in the scheme, then sells them on your behalf — usually as an instant point-of-sale discount rather than a rebate you claim later. This is why solar quotes already look "discounted" compared to the raw hardware and installation cost.

Two things to know for 2026: the STC scheme is on a legislated phase-down, reducing in value each year until it ends around 2030, and the certificate price itself floats with the market. That means the discount you get today is generally larger than what will be available in future years — a genuine reason not to delay indefinitely if you're already considering solar, though you should still compare quotes carefully rather than rush a decision under pressure.

Battery Rebates

Beyond panels, the federal Cheaper Home Batteries Program provides a discount (delivered via STC-style certificates) for eligible battery installations, on top of any state-based battery incentives that may apply in your area. Battery incentive levels and eligibility criteria vary and are worth confirming directly with an accredited installer, since program details and rebate amounts are periodically adjusted.

State-Based Solar and Battery Incentives

On top of the federal scheme, several states run their own programs, though these change frequently:

NSW has run battery and solar incentive schemes at various times, alongside its broader energy savings programs — check current offers via our NSW electricity guide.
Victoria has offered interest-free solar loans and rebates through Solar Victoria in past years, with eligibility often tied to owner-occupier status and property value caps — see our Victoria electricity guide for the latest.
Queensland has periodically run battery booster schemes and rebates for eligible households, particularly for concession card holders — our Queensland electricity guide tracks current programs.
Other states and territories (SA, WA, ACT, TAS, NT) have each had their own battery or solar rebate schemes at different times, generally with capped funding pools that can close once exhausted.

Because state schemes open, close, and get re-funded throughout the year, treat any specific dollar figure you read as a starting point, not a guarantee — always confirm current eligibility and funding status before you rely on it.

Feed-in Tariffs: What You're Actually Paid for Solar Exports

Feed-in tariffs are set by individual electricity retailers, not the government, and there is no single national rate. Retailers compete on export rates the same way they compete on usage rates, and some regulators (like the Essential Services Commission in Victoria and IPART in NSW) publish a "minimum" or "benchmark" feed-in tariff each financial year that retailers must meet or exceed — but many retailers pay more, and some offer tiered or time-varying tariffs that pay more for exports during peak evening periods and less (sometimes near zero) during the solar-heavy middle of the day.

A few practical realities to factor in:

Flat vs time-varying tariffs — a flat rate is simpler to understand, but a time-varying tariff can pay significantly more if you can shift some exports to the evening (e.g. via a battery) or if your system already exports more outside the midday trough.
Feed-in tariffs generally trend downward over time as more households install solar and midday grid supply increases, so don't assume the rate you sign up for will hold indefinitely.
The FiT is only one part of the equation — a retailer with a slightly lower feed-in tariff but much cheaper usage rates and no daily supply charge premium can still leave you better off overall. Always compare the total bill impact, not just the export rate.

This is exactly the kind of comparison that's hard to do by eyeballing plans — small differences in usage rates, supply charges, and export tariffs interact in ways that aren't obvious from a glance.

Working Out Your Real Payback Period

A solar system's payback period depends on system size, your household's daytime energy use (self-consumption reduces your grid bill directly, which is usually worth more than the feed-in tariff), your feed-in tariff rate, and any upfront rebates you're eligible for. Households that use more electricity during daylight hours — running the dishwasher, pool pump, or EV charger in the middle of the day — typically get a faster payback than those who are out at work and export most of their generation. If you're considering adding a battery, the calculation shifts again: batteries store midday excess for evening use, which can be worth more than the feed-in tariff, but the upfront battery cost needs to be weighed against that value.

What This Means If You're Not Going Solar (Yet)

Even if solar isn't right for your household this year, it's worth checking that your existing electricity plan is competitive — retailers frequently offer better deals to new customers than to loyal existing ones. It only takes a couple of minutes to see what you could save in 2 minutes with a free, no-obligation bill check. You can also compare current market offers directly on our electricity deals and gas deals pages, and if you're bundling your household bills, our internet and mobile comparisons are worth a look too.

Rebate amounts, scheme eligibility, and feed-in tariff rates change regularly and vary by retailer, network, and state — the figures and programs described here are general information, not financial advice, so always confirm current offers before signing up.

Steps to Take

Check your current electricity plan against the market — many households are on outdated rates that no longer reflect their solar export or usage pattern.
Get at least three quotes from CEC-accredited solar installers and ask each one to itemise the STC discount separately from the hardware and installation cost.
Confirm which state or territory rebates and battery incentives are currently open in your area, since funding pools can close or refresh partway through the year.
Compare feed-in tariffs across retailers rather than accepting your current provider's rate by default, checking whether a time-varying tariff suits your export pattern better than a flat one.
If considering a battery, estimate your evening usage first — the value of stored solar depends on how much grid electricity it actually displaces.
Run a free, no-obligation check on your current bill to see exactly where you stand before making any changes.

Solar rebates and feed-in tariffs can genuinely cut your power costs, but only if the numbers stack up for your specific household and you're on a competitive plan to begin with. The fastest way to find out is to get your free bill check at /savings — it takes about two minutes and shows you exactly what you could be saving right now, whether or not you go ahead with solar.
